Emmanuel Lecharny resolved DIRMINA-917.
---------------------------------------
Resolution: Not A Problem
This is plain normal. If you brutally kill your process, or unplug your network
cable, the server won't be informed that the client has been disconnected.
If you want the server to be informed that the clients are disconnected, then
the clients have to safely close the sockets they are using.
Note this is not specific to MINA : it's exactly the same problem in C or any
other language.
> IoHandlerAdapter.sessionClosed is not call when the clien close a connection

> Key: DIRMINA-917
> URL: https://issues.apache.org/jira/browse/DIRMINA-917
> Project: MINA
> Issue Type: Bug
> Components: Handler
> Affects Versions: 2.0.3
> Environment: OS:Debian 2.6.32-41
> MINA Version:2.0.3
> Reporter: xieyufeng
> Priority: Critical
>
> My Client Code:
> public static void main(String[] args) throws Exception {
> Socket[] sockets = new Socket[100];
> try {
> for (int i = 0; i < 100; i++) {
> // sockets[i]=new Socket(args[0],
> Integer.parseInt(args[1]));
> sockets[i] = new Socket("*.*.*.*", 8282);
> try {
> Thread.sleep(1);
> } catch (InterruptedException e) {
> e.printStackTrace();
> }
> }
> } catch (Exception e) {
> e.printStackTrace();
> }
> while (true) {
> try {
> Thread.sleep(100000);
> } catch (InterruptedException e) {
> // TODO Auto-generated catch block
> e.printStackTrace();
> }
> }
> }
> where the 100 connection finished,"sessionCreated(IoSession session)" called
> 100 times(It's OK),Then I kill the client process.I found"
> sessionClosed(IoSession session)" only called 33
> times,"exceptionCaught(IoSession session, Throwable cause) " called 65
> times.So I suggest “sessionClosed” is not called every time .
